A low-privileged remote attacker could gain unauthorized access to critical resources, such as firmware and certificates, due to improper permission handling during the runtime of services (e.g., FTP/SFTP). This access could allow the attacker to escalate privileges and modify firmware.

A low-privileged remote attacker could gain unauthorized access to critical resources, such as firmware and certificates, due to improper permission handling during the runtime of services (e.g., FTP/SFTP). This access could allow the attacker to escalate privileges and modify firmware.

A design flaw in the file system management exposes internal system partitions - intended to be hidden - during brief moments when they are mounted by the firmware. These partitions contain sensitive data such as firmware and certificates. Although access to the file system is mediated by a Nucleus layer that supports permission control, these permissions are currently not enforced. As a result, services like FTP/SFTP may inadvertently gain access to critical internal resources, increasing the risk of unauthorized access or data leakage.
